All hours. I firmly believe that if it's hunting season and you can be out there, you gotta be there. The one and only surefire hunting skill is persistance. Since'99 my 8bucks have been killed at 5pm, 1pm, 7am, 3pm, 1pm, 7am, 8am, and 3pm. No pattern there at all that I can see, other than maybe it's a bit light in the final two hours of daylight, but I think that's a fluke created by small sample size.
